Intraocular Cell Migration Inhibition System

Abstract

Generally, an intraocular implant and methods for treating an ocular condition. In particular, an intraocular implant which implanted between an intraocular lens and the surface of the posterior capsule of the eye inhibits migration of residual lens epithelial cells after cataract surgery by providing structural barriers to reduce posterior capsule opacification of the eye.

1 . An intraocular implant comprising:
 an intraocular lens comprising:   an intraocular lens haptic;   an intraocular lens optic; where the intraocular lens optic comprises:   a biocompatible flexible membrane having flat front and back surfaces disposed a uniform thickness apart; the biocompatible membrane comprising:   an aperture; and   a lens; where the aperture contacts the lens at an aperture inner diameter of  1 . 5  to  9  millimeters.   
     
     
         2 . The intraocular implant of  claim 1 , further comprising an annular member coupled to the front surface of the biocompatible flexible membrane, the annular member having an edge which defines the outer boundary of the intraocular implant. 
     
     
         3 . The intraocular implant of  claim 1 , wherein the edge has an external surface which intersects with the back surface of the biocompatible flexible membrane at an angle which produces a corner sufficiently sharp to prevent or inhibit migration of cells toward the center of the intraocular implant. 
     
     
         4 . The intraocular implant of  claim 1 , further comprising patterned surface elements coupled to the back surface of said biocompatible flexible membrane.
